VENT-PIPE SLEEVE.

Application filed Ilay 16, 1923. Serial No. 639,286.

T o all whom t may con-cern:

Be it known that I, JOSEPH IImsHs'rnIN, a citizen of the United Statesof America, residing at the city of Cleveland, county of Cuyahoga, Stateof Ohio, United States of America, have `invented a certain new anduseful Vent-Pipe Sleeve, of which the following is such a full, clear,and exact description as will enable any one skilled in the art to whichit appertains to make and use the same, reference being had to the ac-`companying drawings, forming part of this specific ation. l..

My invention relates to a flashing sleeve for vent pipes or the like,which pass through roofs or other surfaces. Its object is to produce asleeve embodying convenient and effective means for making water-tightadjustable clampingconnection between it reliable and permits the readyclampingin and a surrounding flashing or kthe waterproofing material `onthe roof.

In the accompanying drawing Figure 1 1s La cross-sectional view showingone embodiment of my invention, and Figure 2 1s a top plan 'view` of thedevice illustrated inl Fi ure 1. i

y improved vent lpipe sleeve 1 surrounds the vent pipe 2, and an annularrecess 3 on ythe inner wall of the sleeve forms a space Vbetween thepipe and the sleeve for the insertion of suitable `packing material.

The sleeve 1 is provided with an integral exterior flashing flange 4over which the flashing or waterproofing material 5 may be extended.Sleeve 1 is also provided with a terminal locking flange 6, whichflangehas spaced openings'Y therethrough. The flashing clamping ring 8of annular shape and having sufficient internal diameter to pass overthe terminal flange 6, bears upon the upper surface of the flashingwhich is clamped between it and the flashing flange 4 to form awater-tight union between the flashing and the sleeve. is provided withinwardly extending lugs 12 which cooperate with the exterior of thesleeve to properly position the opposing surfaces of the ring andflashing flange. These pass through openings 7 in the terminal flange 6in the assembling of theparts.

Clamping pressure is applied kto the clamping ringS by means of thethreaded bolts' 9 carried by locking ring 10. This The clamping ringrlocking ring is also annular, having internal diameter slightly greaterthan the diam,- eter of the terminal flange 6, but is provided withintegral inwardly projecting lugs 11, which, while they are adapted topass through openings 7 inthe terminal flange,

bear upon the under surface of this flange when the locking ring 1srotated after application to the sleeve, and the clamping bolts yhavebeen screwed down to pressure to the ring 8. n

p As above indicated the waterproofing ma terial 5 may either be aflashing positioned in the material of the roof below the upper surfacethereof,or,may be a sheet of waterproofing material'such as paper, feltor the like, which constitutes the top surface of the roof.

The arrangement described is krigid and apply clamping position ofwaterproofing material of' varying thicknesses. It also allows of thepositioning of the clamping bolts in the position which may be mostconvenient in the particular installation being made. U

` Having fully described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. The combination of a pipe sleeve provided with a flashing flange anda locking flange, a clamping ring cooperating with the flashing flange,a. locking ring above the clamping ring and having portions engaging thelocking flange, and clamping bolts in threaded engagement with thelocking ring and bearing on the clamping` ring.

2. The combination of a pipe sleeve provided with an exteriorcircumferential flashing flange intermediate its `ends, a clamping ringcooperating with said flange, and means engaging the sleeve above theflashing flange for holding said ring in clamping position.

3.
